Application Form and Guide for a New or Renewed Approval of a Municipal Mechanical Wastewater System

Transcription

1 Municipal Mechanical Wastewater System Introduction The attached form and guidelines outline the information required for an application for an approval or approval renewal of a mechanical wastewater system. The application has been prepared in accordance with the Environmental Protection and Enhancement Act (EPEA) and Approval and Registrations Procedure Regulation 113/93. Please ensure that each section of the application is completed in a concise and clear manner. A wastewater system includes wastewater collection mains, lift stations, wastewater treatment plant, treated effluent storage, treated effluent wetlands, pumping, any treated effluent outfall(s), the treated effluent discharge route, and if applicable, wastewater irrigation systems and lands used for irrigation. For your information, the general steps and procedures that are followed when reviewing and issuing an Approval for a municipal wastewater system is illustrated by the attached flow chart (Figure 1). Of particular note is the fact that the application for this Approval must be advertised by the applicant and that the applicant, upon request, must provide copies of the application to the public. It is therefore important that the application for this Approval contain all the information required and be formatted to facilitate public review. Application for new approvals must contain written confirmation, by a professional registered with APEGGA that all aspects of the wastewater design conform to the requirements of the Regulations under the Act, or a statement identifying and justifying any deviation. The plans and specifications submitted in support of the new approval must also be signed and stamped by a professional registered with APEGGA. All information spaces in this application must be filled in or marked not applicable (N/A). Failure to provide all necessary information may cause the application to be rejected and returned to the applicant. For an EPEA approval renewal, this application must be completed and forwarded to the Alberta Environment and Water, at least six months prior to the expiry date of the existing Approval for the wastewater system. All applications must be forwarded to: Alberta Environment and Parks Regulatory Approvals Center 5th Floor, South Petroleum Plaza Street Edmonton, AB T5K 2G8 Phone: Fax: aep.epeaapplications@gov.ab.ca FOIP STATEMENT: Personal information on this form is collected under the authority of section 33(c) of the Freedom of Information and Protection of Privacy (FOIP) Act and will be used to administer the Environmental Protection and Enhancement Act and its associated regulations.
